Asymmetric dual-band UWB / 60 GHz demonstrator

This paper describes a pragmatic approach on the up-conversion of WiMedia compliant UWB signals into the 60 GHz band. This dual band concept is based on propagation measurements at {3.1-10.6} and 60 GHz. Due to stringent frequency regulation, UWB systems operating in the 3.1 to 10.6 GHz bands are both bandwidth limited and power limited. Therefore, many potential users hesitate to deploy this technology. Up-conversion to the 60 GHz band and enhanced baseband parameters can make UWB technology more reliable and hence, more attractive. An experimental system based on a commercially available UWB development kit and IHPpsilas 60 GHz chip-set has been developed. The system architecture is described. Measurement results indicate that this combination may be interesting for many applications.
